Official 90-day evaluation versions of Rhino 5 here. If you don't want to buy a $995 license of Rhino just for this tutorial, you can download an officialĩ0-day evaluation versions of Rhino 6 here, and the (I'm using Rhino version 5 because that's the license my company has, but Rhino version 6 is the most recent.) (If you have better ideas, don't be afraid to mention them in the comments!)įirst, get a copy of the 3D CAD package Rhino. There are obviously many ways to get this effect (since a lot of people do it) but I'm going to show you the one most accessible to me. Step 3: Downloading Rhino and Grasshopper.To do that, we're going to have to download two new pieces of software. So that's why I started this journey: to learn how to take any CAD shape I can design and fill it with complex '3D Print looking' semi-repeating structures, and then print it. I work in 3D printing but had no idea how to automatically generate the complex '3D Printed look' that most of the industry uses as our standard! That's like a leather worker having no idea how to make a cow. I realized I could figure out how to make the faceted one on the right, by just reducing the poly count in my design software:īut I realized I had NO IDEA how to create that complex bunny on the left! Let's take those two pink bunnies as an example. (That last image of the bunnies is from user u/tawmaraff in the fun subreddit r/3Dprinting, which is worth checking out for more of this sort of thing.) Semi-random, sort-of-repeating structures that could NEVER be machined, inside a larger controlled shape, is how we let you know something is 3D printed.Īs an industry, it's sort of become our 'aesthetic': So recently I was at a trade show and I saw a LOT of things that looked like this in a competitor's booth:Īnd if you've been in the industry a while, you know that's sort of the 3D printing 'look', right? If you picked up an object and the outside looked like this, you would immediately know where it came from:Īnd if you picked up something that looked like this: Things are going to get weird from here on out. You'll have to download a few random pieces of software, do visual coding of computer algorithms, and there's even some Maths. We show how to use Grasshopper and Rhino to automatically generate complex Voronoi structures ready for 3D printing.Īt the very start, I want to let you know: this is going to be one of the hardest, most esoteric 3D printing tutorials I've written yet.
